My goal for this post is using the simplest and fastest way to teach you the basics. So let’s get going.
When we talk about exposure we simply mean the brightness or darkness of a photo. It seems so simple to take a photo that is correctly exposed (has the proper brightness or darkness), but in reality, it can be quite a challenge.
If you’re reading this, it probably means that you currently use the automatic settings of your camera. It means that the camera entirely controls the exposure of the picture. When you shoot on automatic mode, your camera selects an ISO setting, an aperture setting, and a shutter speed. Automatic limits your ability to take more creative, beautiful, unique photos. But when you shoot in manual setting you can control all those three features yourself.
I shot this picture below just to show you the difference.
So to understand how your camera works you need to learn about three parameters that control exposure:
ISO – the measure of a digital camera sensor’s sensitivity to light. ISO number (up or down) represents a doubling or halving of the sensor’s sensitivity to light.
Aperture – the size of the opening in the lens when a picture is taken. aperture setting is indicated by the f-number.
Shutter Speed – the amount of time that the shutter is open and is measured in fractions of a second.
Here’s also cheat sheet so you can better understand how all those three components work together
Take out your camera and start practicing and never forget
I hope you enjoyed this little lesson. See you soon 🙂
